Modbus Register Map - iPFC
Please find the attachment.
Article 4.6.2.26S: Is APFC440 or iPFC is suitable for controlling PF for the Solar application.
If the APFC is connected to Solar application, then customer has to ensure that it current has to flow in forward direction. If customer want to use APFC for both EB & Solar applications as Import & Export then APFC will not support. For APFC ...
Article 4.6.2.2S : Advantages of iPFC440 power factor controller.
It is not just a PF controller but also a true multifunction meter. It has V, A, Hz, W, VAR, and Wh parameters in addition to PF. Hence this product is truly power-packed. It also has an RS485 communication option. This product can be used in all ...
Article 4.6.2H : Why 3 phase and why not 1 phase in iPFC ?
In 3 phase, sensing will give accurate results. In 1 phase, there will be a chance to miss the phase angle.
Article 4.6.2F : What happens when the load is heavily fluctuating?
As the iPFC has 15 seconds average, it won’t capture the exact value.
Article 4.6.2G : Where we have to connect iPFC in field ?
It should be installed next to transformer and before the capacitor bank.
Article 4.6.2E : What are the faults can be detected by iPFC?
Over Compensation, Over voltage, Under compensation, Over Current, Under Current, Over Harmonics for voltage and current.
Article 4.6.2D : How many stages of iPFC are available ?
4, 6, 8 & 12 stage iPFC are available.
Article 4.6.2A : How to check IPFC meter error in meter ?
Go to meter configuration and make it settings enable from 42 to 47 options to find error in meter, like under current, over current, under compensation, over compensation, over voltage, under voltage and other warnings.
Article 4.6.2B : Under current error in IPFC meter
under current error will show because of there is no minimum load at all three phase. If it clear then only it will work in auto mode.
Article 4.6.2C : Under Volt Problem in iPFC
New settings provided for UNVOLT issue New settings done in setup page of IPFC meter- 1. "A.d"- to be set to 60 seconds. 2."O.W"- Other warnings to be disabled. Please do the same settings in all other IPFC meters at site.
